Cube Merge Royale

This one looks a bit like Ball Merge Rush, but instead of numbers you're working with coloured cubes – red, blue, green, yellow, purple. The board is a square grid, maybe 5x5, and cubes drop from the top one by one. You slide them left or right and tap to drop them into a column. When a cube lands next to two or more cubes of the same colour (touching sides), they all merge into a single cube of a new colour – for example, two reds become orange, two blues become green, following a fixed colour chart. That new cube then checks its neighbours for more matches, which can start a chain reaction.
Every merge gives you points, and larger chains pay out more. But here's the twist – you're not playing alone. There's a ghost opponent on the other side of the screen, or maybe a friend's recorded run. Both boards fill at the same pace, and whoever reaches the target score first wins the round. If your board fills up completely before that, you lose instantly.
Each level gives you a fixed number of drops – say, 25 to start. The opponent's drops are simulated at a similar speed, so you see their progress bar creeping up alongside yours. No timers, but the pressure comes from watching that bar move. You can't rotate cubes, only drop and merge. No power‑ups, no special cubes – just pure merge logic and a bit of speed.
Later levels introduce more colours, faster drop rates, and a tougher opponent who seems to get lucky merges more often. You have to think quickly because every second you hesitate, the other side gains ground. It's competitive but fair – the mechanics stay clean, and losing never feels cheap. You just need to spot merges faster and plan ahead. 🟦🟥
